struction of window by which the window is made in two parts so mounted ina window-frame that one art counterbalances the other, the parts being so connected that they may be swung upon supporting levers so as to secure any desired degree of opening between the window-sashes and the casing. The counterbalance of the sashes is secured without the use of weights of any description outside of the sashes themselves and furthermore, the sashes are so disposed in the Window-frame that when the window is closed the two sashes lie substantially in the same plane, thus presenting a continuous and practicall unbroken surface to the weather, which a ds much to the architectural efiect ofthc structure. The construction of window described also permits the use of a much thinner window-frame than is the case with constructions in which the two sashes are in different planes and the reveals in the masonry ma therefore, be deeper with the same thic ess wall, which also adds much to the architectural efi'ect of the structure. I

v I am aware that constructions have been employed in the past in which the two sashes are connected by levers so as to counterbalance each other and I do not, therefore, claim broadly as my invention this arrangement. On the other hand, my

invention consists in improved structural features by which' the results described above are secured, aswell as a construction facilitating the use of iron or steel in the window-frame and sashes for the construction of fireproof windows. In carrying out my invention, the sashes and frame are so constructed that there are inter-locking joints all around each sash, both with the window-frame and the other sash, as a result of which weather-tight joints are secured. My invention also contemplates an lmproved means for clamping the sashes together when the window is closed and means by which the sashes may be swung inside of the frame, so that the outside of.

the glass may be washed. By my invention I also provide an improved shade support- 1ng arrangement, so that shades carrled by the sashes are positively held in place and serve as awnings when the window is open.

The above as well as other features ehar-' acterizing my invention will appear more clearly from the accompanying drawings, which are as follows:

Figure 1 shows in inside elevation a window and frame constructed in accordance with my invention;

Fig. 2 is a vertical transverse sectional view taken through the parts shown in Fig. 1 along the line 2-2;

' Fig. 3 is a horizontal sectional view taken transversely through the upper sash shown in Figs. 1 and 2;

Fig. 4 is a view similar to Fig. 3 through the lower sash shown in Figs. 1 and 2;

Figs. 5 and 6 are detail views of one of the supporting levers illustrating how the said lever is connected to the window-frame and Fig. 10 is a diagrammatic view showing the nature of operation of the sashes when the window is opened.

Similar numerals refer to similar parts throughout the several views.

As shown in the drawings, the windowframe is made of a channel section 1 constructed so that its flanges extend outwardly to engage the masonry of the building. The channel section 1 has secured across its inner face at the top of the win-. dow-frame an angle bar 2 to serve as a stop for the upper sash 3 to close the joint be tween the sash and the frame to exclude rain and cold. The lower portion of the frame is of such conformation that an upwardly extending flange 4 is provided to enter be,-

tween the members 5 and 6 of the lower rail of the lower sash 7. The uppersurface ofthe bottom of the window-frame is inclined downward, as indicated, to shed the water which dropsupon it fromthe lower sash and, if spray should be projected into the air chamberbetween'the members 5 and 6 and the flange 4, it will drain into the inner surface 8 of the bottom of the window-frame which is curved upwardly, as indicated, and be caused thereby to flow through the drainage openings 9 into the outer part of the window-frame and thus away from the inside of the building. The members 5 and 6 nel which it occupies.

upper sash 3.

are made a snug fit against the flange 4 so that it is with difficulty that any spray would be projected through the joint. The side members of the window-frame are of channel construction, as indicated in Figs. 3 and 4, and have formed longitudinally.

therein in their exposed faces shallow grooves for receiving channel bars of spe cial conformation, as indicated at 10 and 11' in Figs. 3 and 4, the open sides of the chair nels being toward the outside of the room for the upper half of the window and directed toward the room for the lower half of 'the window.

The lower sash 7 is formed of vertical channel sections 12 and 13, so made that the outer flanges enter the channels in the channel bars 11 when the lower sashis closed and the outer flanges of the channel bars 11 enter the channels in the channel bars 12 and 13,

the conformation of the parts being such that for the closed position of the sash each channel bar engages the bottom of the-chan- The upper rail of the lower sash is formed of a channel section 14 open toward the. outside of the building to receive the outer flangeof a channel sec tion 15 constituting the lower rail of the The channel section 15 is provided with a downwardly extending outer flange 16 which engages the outer surface of the channel section 14 immediately above the glass 17. The channel sections 14 and 15' are so conformed that a considerable air space 18 is left between them, thus'permittingfree expansion and contraction of v the metal parts without changing the close,-

ness of the fit of. the weather oints. willbe noticed that the upper rail 14 of the lower sash and the lower rail 15 of the upper sash engage each other at three points, thus making it practically. impossible for the weather to beat in from the outside of the .not present.

.7 as a resu v ed. Washers 30 and 31 are provided bewindowinto the room. The members 5 and 6 constituting the lower rail of the lower sash also form betweenthem a considerable air s ace 19, and the top rail of the upper sash is made of metalsections which inclose a considerable air space 20, which air spaces are of great advantage in connection with fire roof windows, since they act as a fireretar ant and prevent the warping and twist:

ing out of shape of the frame as soon as it would be accomplished were" the air spaces It is not essential that air spaces be provided between the channel bars 10 and the channel bars 26 and 27, or between the channel bars 11 and the channel bars 12 and 13, since the deep interlock between these sections provides that the window could not be twisted or warped clear of the frame by the application of heat. If for any reason air spaces are desired at the sides of 'the shell, they may easily be provided by increasing the sizes of the channel sections just referred to, which will, of

course, reduce to a certain extent the size of the glass for a glven size Window-frame.

The side members 26 and 27 of the upper sash are formed in a manner similar to the side members 12 and 13 of thelower sash, thediflerencebeing that the open sides of the channel are faced inward instead of out ward. When thetwo sashes 3'and -7-are of i about the same height, as isfusually the case,

the joints between the upper channel sec tions 10 and the lower channelsections, 11 occur at about the. middle of the vertical sides of the window-frame 1 and, at that point, the outstandingportions of the channel bars cut away to receive a washer 21, which forms a support for the stud22 used 'toform the pivot ofthe lever 23. One of these levers is mounted upon each. side of the window and its ends are connected by bolts 24 and. 25 with the upper and lower sash, respectively, the lever-arms between the pivot 22 and the'pins 24 and 25 being equal. The pivot bolt 22 and the washer 21 are preferably of bronze and the bolts 24' and 25 are threaded into bronze bushings 28 and 29,

which form the bearing surfaces within the lever23, so that the wearin'gsurfaces are bronze against iron or steel t roughout and thus the ossibility of the 'oints freezing 7 it of rusting of t e-iron is avoidtween the lever 23 and the channel bars 27 and 13 for the same purpose. bars 12 and 13 of the lower sash and the "channel bars 26 and 27 of the u er sash are formed with sufliciently wide .0 f'annels, so that whenthe window is closed the levers 23 arein vertical position and lie almost'wholly within the channels formed intjthese bars, 2 thus presenting a comparatively unbroken" thebui d surface on the inside 0 ing'up to nearly the middle of the gf pper sash.

The channel The upper sash 3 has secured to the ends of its upper rail, as indicated more clearly in Fig. 1, two rollers 32 which project around the backs of the channel bars 10, thus holding the upper ends of the channel bars 26 and 27 of the upper sash securely in engagement with sai channel bars 10. The rollers 32 are preferably of bronze and their rolling action results in comparative ease of operation, when the sash is opened or shut and the further advanta e also that the paint or enamel on the bac s of the channel bars 10 will not be injured as would be the case if solid pins were used instead of said rollers.

The lower sash has mounted upon its bottom rail two bronze pins 33, as more clearly shown in Fig. 4, which normally project so as to lie just outside of the backs of the channel bars 11, as a result of which the lower ends of the channel bars 12 and 13 of the lower sash are held securely in enga ment with said channel bars 11. The pins 33 are slidabl mounted in housings 34 secured to the lower rail of the lower sash, springs being pro ided in the housings to hold the pins in place. The pins 33 are extended through the housings 34 into finger holds 35, by which thepins may be withdrawn from back of the channel bars 11- when it is desired to swing the lower sash into the room away from the channels 11 so that the outer surface of the glass 17 may be washed. When the sash. are in closed position, the lower rail of the upper sash and the upper rail of the lower sash are clamped together by means of the cam 36, pivotally mounted at 37 upon a bracket 38 secured to the upper rail of the lower sash which cam 36, en ges a catch 39 carried by the lower rail 0 the upper sash in such a manner that the cam surface moves the two rails laterally into tight clamping engagement when the cam is moved upon its pivot 37. This action is more clearly shown in Fig. 9.

The operation of the device described above will be more readily understood by reference to Fig. 10. When the window is shut the two sashes are in vertical position, as are also the balancing levers 23. When it is desired to open the window, the catch 36 is released and, by moving-the bottom of the upper sash outward, the levers 23 being pivoted to the frame 1, force the top of the lower sash inward a sufficient amount so that the two sashes clear each other before the rotation of the levers 23 cause any vertical motion of the sashes. Continued motion of the levers 23 in the same direction causes the upper sash to be lowered and the lower sash tobe raised, which operation may continue until the upper sash rests against the lower sash and is practically at the same height as the lower sash, as indicated in dotted lines in Fig. 10, which position is the one assumed by the sashes when the window is wide 0 en. I

It is apparent that the sashes may be le t in any intermediate position that is, desired and, since any wind that may be blowing exerts equal and opposite thrusts upon the two sashes, these forces are exerted upon the f tion is necessary, but it is undesirable to permit a large quantity of cold air to enter the room.

In order to swing the upper sash 3 into the room, for cleaning the outer face of the glass mounted therein, provision is made to remove a' portion of the channel bars 10 as follows: The portion of the bar, as shown at '10 in F igs. 8 and 10, is provided with inclined upper and lower ends which fit the adjoining ends of the main channel bar 10, such portion 1O being removably held in place as follows: The lower end of the section 10 is provided with a bolt 40 which extends through the channel' section 1 and has mounted upon it between said channel section 1 and its head 41 a spring 42, which normally exerts a thrust upon the section 1O holding it into the longitudinal groove formed in the web of the channel section 1. The upper end of the section 10 is provided with a lug 43 extending through the channel section 1, which lug has formed therein an opening adapted to be engaged by a taper pin 44, as shown in Fig. 3. The engagement between the lug 43 and the pin 44 holds the upper end of the section 10 in the channel formed in the web of the window-frame section 1. The bolt 41 and the lug 43 are surrounded by housings 45 and 46 to protect them from the masonry built into the channel section 1 between its flanges. To lower the upper sash 3 into the room for cleaning purposes, the window is first opened a suflicient amountso that the section 10' may be moved from its normal position. Then the taper pins 44 are drawn out, their removal from the channel section 1 being prevented by lugs or pins 47 projecting therefrom. Then the u per end of the section 10 is forced out o engagement with the channel section 1 a sufficient amount to clear the lug 43 from the said section 1, and the section 10' is turned against the action of the spring 42, so that it occupies the position indicated in dotted lines in Fig. 10. Then, the window is opened farther, so'that the upper end channel bar 10. a

The upper rail of the upper sash has mounted thereon, as indicated, a spring roller 48 for supporting a shade 49. The lower edge of the shade is secured to a crossrod or bar 50, from which a cord 51 extends downward through an eyelet 52 secured to the lower rail of the upper sash,from which eyelet the cord passes upward around the outside of the shade on the roller 48 and down to the cross-bar 50, where itis secured to the upper end of the cord 51, thus making a continuous belt through the eyelet 52 and around the roller 48, which positively holds the shade 49 in any position to which it ma be adjusted without permitting it to sag or op, when the sash is moved to an inclined position, as indicated in Fig. 10. The lower sash issimilarly provided with a roller 53 which supportsa corresponding shade in a similar manner on the inner surface-of the lower sash. The'cross-bar 50 may have a screweye inserted into it at about its middle position, or the ends of the cord may be joined through an eyelet inserted through the centravlvportion of the bar, as desire I ile I have shown and described above a window in which the sashes are of substantially the same size, my invention is not limited to this proportion, since the upper sashma if desired, be of much less eight thant e lower sash, inorder to secure the so-called transom efi'ect. For this construction, the parts will be so proportioned that the supporting levers woul operate the upper sash 1n the same manner as though both sash were of the size of the upper sash,

thus bringing the ugger sash to a position so that its top is an tantial ly alined with the to of the lower sash when the window is wi e open. a For this arrangement, in order that the weights of the two sash may be equal; the upper sash may be provided with additional weight by fillmg in the hollow sections of the upperrail and the channelsof the remaining rtion of the frame of the sash as ui While I have s own my invention in the particular embodiment herein described, it will, of course, be understood that many equivalents may be employed instead of the exact construction shown withoutdeparting from the spirit of my invention.
